There were two things I have wanted to do for some time now. The first was to come up with a way to quickly and easily set up a DarkPAN mirror so that we would have more control over our dependency chain at work. The second was to make a portable CPAN proxy service, so that I can always have access to my favorite modules, even if the machine I’m working on has no Internet access. Last week, I finally had a few ‘rount tuits’ to spend on this type of background itch, and the result is dpanneur (for dépanneur, French Canadian for convenience store). Here it is.
NoSQL is a new way to think about persistence. Most NoSQL systems are not ACID compliant (Atomicity, Consistency, Isolation, Durability). Generally, most NoSQL systems have, Denormalization, Eventual Consistency, Schema-Free, and Horizontal Scale
Before you do anything else install an opcode cache like APC. Wordpress really likes this type of caching, see this slide for the results. Set the timezone, to make sure conversions aren’t being done all the time. Make sure you are cpu-bound, NOT I/O bound. Otherwise, speed up the I/O. Then strace your webserver processs. There are common config issues that you can spot in your strace code. grep for ENOENT which shows you “No such file or directory” errors.
Why is social media and social networking essential to you and your business? (because it will drive sales, but there’s very few analytics for ROI on social networking and social media) Relying on advertising is no longer working for print newspapers and television. So why do we think it will work on internet media?
What is confoo? It is the sequel to the PHP Quebéc Conference (2003 – 2009). This year PHP Quebec decided to team up with Montreal-Python, W3Quebéc and OWASP Montréal to produce confoo. And now, on to Mark Pilgrim of Google speaking on HTML5.
Start planning your blog posts for Ada Lovelace day now (March 24th) To that end, I would like to point out all the women currently in science and tech fields that I admire and think are doing great things. I think it would be great if everyone, male or female, made a list like this
One of the things I love about Git is how I can add branches from remote repositories in mine at will without fearing messing up anything. The remote branches will not clash with mine, even if they share the same names, because they are referenced as repository/branch. However, as for anything else, you can still poke yourself in the eye if you try hard enough…
A couple weeks ago I did a short blog post about SAN storage failures and how people are blinded by all the bells and whistles that are supposed to make storage arrays 100% reliable and failsafe. My conclusion was that there is no way to avoid storage failures, and that a better way is to anticipate those failures and be ready to handle them with minimal service impact.
Applying binary logs to a MySQL instance is not particularly difficult, using the mysqlbinlog command line utility. Turning off binary logging for a session is not difficult, from the MySQL commandline, if you authenticate as a user with the SUPER privilege.sometimes you want to apply binary logs to a MySQL instance, without having those changes applied to the binary logs themselves. One option is to restart the server binary logging disabled, and after the load is finished, restart the server with binary logging re-enabled. This is not always possible nor desirable, so there’s a better way, that works in at least versions 4.1 and up
Here’s the future of MySQL, Drizzle, Monty Program, the Percona fork, etc. The best product management strategies… should we be lightweight for the web, plug-in oriented like Drizzle? Should we follow Monty’s giant-killing roadmap? Should we focus on performance-oriented patches? The best product management strategies will win. They can’t win alone. Will they be backed by appropriate investments from effective developers? Effective developers are the ones who convert winning product management strategies into working products. You can’t get there without them and I’ve seen lots of great strategies fail that test (including my own actually). And there can be more than one winner.
